Thiophene-diazine molecular semiconductors: Synthesis, structural, electrochemical, optical, and electronic structural properties; Implementation in organic field-effect transistors

The synthesis, structural, electrochemical, optical, and electronic structure properties of a new azinethiophene semiconductor family are reported and compared to those of analogous oligothiophenes. The new molecules are: 5,5′-bis(6-(thien-2-yl)pyrimid-4-

n-Type Thiophene Semiconductors

The new fluorocarbon-functionalized and/or heterocycle-modified polythiophenes, in particular, α,ω-diperfluorohexylsexithiophene DFH-6T can be straightforwardly prepared in high yield and purity. Introduction of such modifications to a thiophene core affords enhanced thermal stability and volatility, and increased electron affinity versus the unmodified compositions of the prior art. Evaporated films behave as n-type semiconductors, and can be used to fabricate thin film transistors with FET mobilities ?0.01 cm2/Vs—some of the highest reported to date for n-type organic semiconductors.

Desymmetrization of dichloroazaheterocycles

3,6-Dichloropyridizine 1a was converted in good yield into its mono-iodo derivative 1b when treated with a mixture of hydriodic acid and sodium iodide. Pure samples of the mono-iodo derivatives 2b, 3b and 4b could not be obtained from their corresponding dichlorinated precursors with these reagents. Compounds 1b and 4b underwent palladium catalysed Suzuki, Sonogashira and other coupling reactions.
